TIRE-REPAIRING DEVEGE.

To all whom it may concern:

lie it known that l, FORREST B. DUNLAI, a citizen of the United States, residing at county of Tulsa and State of useful Improvements in Tire-Repairing Devices; and I do hereby to be a, full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to .make and-use the same.

This invention relates to improvements in a tire repairing device and more particularly to a device especially shoe-"or casing in sucha position that a patch or the like may be readily applied to the inner surface thereof.

Another object of .this invention is the provision of a base having formed thereon a block adapted to supportdthe casing or shoe in such a manner that the inner surface thereof will be exposed outermost, so that a hole or the like in the shoe or casing may be readily repaired.

A further object ot n'ovision ot' clamps upon the base adapted to hold the shoe or easing under a tension u on the block.

A still further object oi. this invention is the provision ot a tire repairing device 0 the above stated character, which shallv be simple, durable and etiicient, and which may be manufactured and sold at a comparze tivelv low cost. I.

With these and other objects in view as will become more apparent as the description proceeds. the invention consists in certain novel features of construction, combination and arrangement of parts at will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the fol lowing description and accompanying drawings, in which: s

Figure 1. is a pairing device with my invention, Fig; 2 is a similar view illustrating the initial position of the tire when securing the same upon the block,

Fig. 3 is a side elevation of one of the side elevation of a tire reconstructed in accordance Fig. 4: is a plan view of the device with the tire clamping bars removed,

Specification of Letters Eat eat.

declare the following ing member for adapted for holding a this invention is the Patented June 17, 191.9.

Application filed February 8, 1918. Serial No. 216,053.

- Fig. 5 is an end elevation illustratingthe clamping members securing the tire upon the base;

Fig. (3 is a detail view illustratingthc means for adjustahly and hingedly connecting one end of one of the clamping bars to the base,

Fig; 7 is a transverse sectional view illustrating the curvature of the block,

Fig. 8 is a perspective view of a shoe or casing.

Referring in detail to the drawings, the numeral 1 indicates a base of elongated formation having enlarged ends 2. The base a spread- 1 has formed intermediate its ends a casing or shoe supporting block 3, which is of areaate formation in cross section to conform to the contour of a shoe or casing. Straps are hinged to pintle bearings 5 by pintles 6 and the pintle bearings one edge 01": the enlarged ends 2 of the base 1. The straps 4 are provided'with a plurality of relatively spaced openings 7 to receive the reduced ends 8 0t clamping bars 9. The clamping bars 9 have heads formed upon their reduced ends for retainin the reduced portions within the openings 'a' of the straps L. Handles 11 are secured to the other end of the clamping bars 9.

Locking plates 12 are secured on the ends 2 of the base 1 on the opposite edges from the straps 4 and are provided upon their inner edges with a plurality of upwardly directed notches 13 for the purpose of receiving theclamping bars 9 adjacent the handles 11.

When desiring to applythe casing or shoe 14. to my invention, the spreading member 15 is positioned within the casing or shoe .0 as to spread the edges or head portions hereof. The spreading member 15 has cut away port ions 6 at each end thereof to form shoulders 17 adapted to engage the inner edges 0? the beads ot the casing or shoe.

5 are secured upon upon the other clamping plate 12, it will therefore be seen that the inner surface of the shoe or casing is disposed and trans versely curved so that'new fabric or patches may be readily applied to the inner surface of the shoe or casing so as to repair holes or the like that may be upon the inner surface thereof.

'While I have shown and described the preferred embodiment of my invention, it

will be understood that minor changes in Having thus described my invention, what I claim is':

A tire repairing device comprising a base, a supporting block upon said base for engagement with a tire, straps hinged to said base, clamping bars adjustably connected to the straps and dapted to overlie the tire, and clamping plates secured to the base and adapted to receive the clamping bars.

In testimony whereof I ailix my signature in presence of two witnesses.
